This photo of Jacob and Emilia shows how a fake bokeh can be used to minimise distractions in the background of a picture.
Bokeh refers to the out-of-focus area of a photo, which is the result of using a large aperture and shallow depth of field.
In this case, because Jacob was behind Emilia, it was necessary to use a smaller aperture to get them both of focus. This however meant that the chair and other paraphenalia in the background were also pretty much in focus, creating something of a distraction.
To create the bokeh I used Photoshop to select the background and add gaussian blur to simulate the effect. Whilst this doesn’t remove the distraction completely it does minimise it, focusing the viewer’s attention on the children.
